ES149226U - Piezoelectric ignition device (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Piezoelectric ignition device, with an anvil, at least one piezoelectric crystal inserted in a bushing body, a firing pin and a hammer under the force of a firing spring that is provided with an appendix that protrudes laterally outwards and that by a force that it attacks on the free end of the appendix of the hammer it can be displaced to tension the hammer spring, these parts having been coaxed together in a folded casing of at least one sheet metal cut, the direction of tension of the hammer and its opposite working direction being to each other, for which after moving the hammer on a given path under tension of the striker spring resting against the hammer, the coupling between the attacking force to tension the striker spring and the hammer is released, so that the latter strikes on the hammer, characterized in that it is disposed in a gas-heated appliance, with a gas taps r This means that, when moving its graduation member from the disconnection position to the ignition position, the force is simultaneously transmitted to tension the striker spring by means of a traction hook which is connected by force connection with the member. of graduation on the appendage of the hammer and by which the movable traction hook is provided parallel to the longitudinal axis of the ignition device, of a seating surface to free the coupling between the traction hook and the hammer.
